Tallulah Willis strips down to talk about body dysmorphia

Tallulah Willis is speaking frankly about her struggles with self-esteem and body image.

The youngest daughter of Bruce Willis and Demi Moore stripped down to her bra and underwear while opening up about those subjects for Stylelikeu's "The What's Underneath Project."

"I struggled a lot when I was younger. I'm diagnosed with body dysmorphia [because of] reading those stupid f----ing tabloids when I was like 13, feeling like I was just ugly, always," Willis, 20, says in the video. "I believed the strangers more than the people who loved me, because why would the people who love me be honest?"

"That made me start to dress really with showing off my boobs and my butt, and showing off those things that I was getting attention for... It took me until like a year ago and I remember specifically one day putting on a button-up and buttoning it all the way up to my neck and having long pants on that weren't tight ...and feeling so beautiful," she explained. "That was a mindf--k for me, the fact that all the attention had to be on my face and that was so scary for me, because I already wanted to distract people. And by the time I realized that wasn't who I was anymore, it was like I was trapped in this body and I hated that I was sexy."

"I started starving myself and losing a bunch of weight and I got down to like 95 pounds," she added. "When I lost my curves and my boobs shriveled up into nothing, and I had no shape and I was just saggy skin everywhere, I was like 'Hey, believe me now?' But I viewed super-skinny me as smart, intelligent. I was able to have the physical transformation so everyone could see me differently."

Now, she hopes she can help others by sharing her story.

"If I can use any of the pain that I've gone through, and if ... when other girls read it they can be healed a little, even if it's the smallest piece, by something I've written or the way I've written it, that's very, very important to me," she said.
